Abstract
A power cable termination device for a high voltage direct current gas-insulated switchgear including: an outer housing made of an electrically conducting material, connectable to the switchgear; a terminal portion of a power cable, the power cable including an electrical conductor, a circumferential electrically insulating layer, and a circumferential conductive shield which is stripped off along a first part of the power cable; an electric field grading system including a resistive field grading material layer arranged circumferentially around the power cable to axially cover the edge of the conductive shield where the conductive shield is terminated, the resistive field grading material layer being in electrical contact therewith, and a connection device connectable to the gas-insulated switchgear and arranged to provide mechanical support and electrical contact with the gas-insulated switchgear.
